A psychometric function is an inferential psychometric model applied in detection and discrimination tasks. It models the relationship between a given feature of a physical stimulus , e.g. velocity, duration, brightness, weight etc., and forced-choice responses of a human or animal test subject.
According to the Atkinson-Shiffrin memory model or multi-store model, for information to be firmly implanted in memory it must pass through three stages of mental processing: sensory memory, short-term memory, and long-term memory. [7] An example of this is the working memory model.
It is a computer-aided cognitive assessment system consisting of a battery of neuropsychological tests, administered to subjects using computer screen, a dedicated keyboard and a graphics tablet as stimulus and response media, respectively. The nine tests in CFS examine various areas of cognitive function, including:
Computational psychometrics studies the computational basis of learning and measurement of traits, such as skills, knowledge, abilities, attitudes, and personality traits via mathematical modeling, intelligent learning and assessment virtual systems, [6] and computer simulation of large-scale, complex data which traditional psychometric ...
Fluid intelligence involves the dorsolateral prefrontal cortex, the anterior cingulate cortex, and other systems related to attention and short-term memory. Crystallized intelligence appears to be a function of brain regions that involve the storage and usage of long-term memories, such as the hippocampus. [30]
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
Memory is a very broad function which includes several distinct abilities, all of which can be selectively impaired and require individual testing. There is disagreement as to the number of memory systems, depending on the psychological perspective taken.
The n-back task captures the active part of working memory. When n equals 2 or more, it is not enough to simply keep a representation of recently presented items in mind; the working memory buffer also needs to be updated continuously to keep track of what the current stimulus must be compared to. To accomplish this task, the subject needs to ...
